Wealthiest Donors Gave 9 Percent of Their Income in 2007, Study Finds

Giving to the arts as a share of all high-net-worth philanthropy decreased from 13.2 percent to just 4.2 percent in that period.

Slightly more wealthy households gave to social-service groups in 2007 than two years earlier, but the size of their gifts remained small. Eighty-one percent of households donated to such charities, the most of any cause, but their average gift was only $3,578.
